Quality of services

The main focus of congestion control and quality of service is data traffic. In congestion control we try to avoid traffic congestion. In quality of service, we try to create an appropriate environment for the traffic. So, before talking about congestion control and quality of service, we discuss the data traffic itself.

The study has been conducted on a sample of (1000) customer was randomly selected from the customers of all surveyed banks. The quality of service was measured by applying the gap model (the difference between the customers’ perceived, and their expected quality).data required for this study has been collected by a question0naire which was designed for this purpose.

The IEEE 802.16 std. includes medium access control (MAC) and physical (PHY) layer specifications and is consider to be a promising technology. Bandwidth reservation is employed to provide quality of service (QoS) to guarantee different services specified in the standard. A bandwidth request/grant scheme is defined in the IEEE 802.16 standard.

In this paper, we propose a framework to adaptively meet the expected Quality of Service (QoS) attributes of web services under high number of requests using service replication. The proposed framework uses Holt’s Linear and Exponential Smoothing (HLES) time series technique to smooth and provide short term predictions of the response times and the requests arrival rates for the accessed web services.

In providing new telecommunication (telecom) services, the requisition for quality of network is more and more popular and sophisticated with high bandwidth, small value of delay time or packet loss etc. To assure the quality of network, the scheme of Quality of Service (QoS) routing algorithm based on local state information have recently been researched as a promising alternative to the currently deployed global QoS routing schemes.

Wireless and Mobile Internet have changed the way people and businesses operate. Communication from any Internet access point, including wireless networks such as UMTS, GPRS or WLAN has enabled organizations to have a mobile workforce. However, networked applications such as web, email, streaming multimedia etc. rely upon the ability of timely data delivery. The achievable throughput is a quality measure for the very task of a communication system, which is to transport data in time. Throughput is thus one of the most essential enablers for networked applications.

Improving Grade of Service (GOS) While Reducing RF Channels Wireless service providers are adopting new deployment strategies to reduce network costs and improve quality of service. In one urban market, a major national wireless service provider has improved network traffic loading and significantly boosted network RF performance by centralizing radio equipment and deploying digital RF transport technology. The digital RF transport systems operate in simulcast mode and reproduce the signal at radiating points throughout the network.
